The Iraqi government has used a curfew in Baghdad to help security forces control surging violence in the capital.

People and cars were ordered off the streets Friday after clashes broke out between insurgents, Shi'ite militia and U.S. and Iraqi security forces near the heavily-fortified Green Zone in Baghdad. Several people were reported killed in the incidents. Prime Minister Nouri al-Maliki's office said the Baghdad curfew was lifted two hours after it began.

Elsewhere, a bombing in Basra and one in the village of Hibhib killed a total of 15 people and wounded 30 others.

The U.S. military said coalition troops killed four foreign terrorists and wounded one Iraqi insurgent during a raid Friday near Fallujah, west of the capital.

U.S. casualties continued to mount, as officials announced that five American servicemembers have died since Wednesday, including two soldiers whose vehicle hit a roadside bomb southeast of Baghdad Friday.
